RADIATOR FOR HEATING BUILDINGS. p

SPECIFICATION forming part of Letters Patent No. 499,181, dated June e,1893.

Application filed June 14, 1890.

To all whom it may concern:

Be it known that l, WILLIAM G. BAKER, a citizen of the United States,residing at the city and State of New York, have invented beenintroduced within said vertical pipes extending nearly to the top, forthe purpose of promoting a circulation of the steam passing through suchradiator by driving out, before it the atmospheric air in the verticalpipes. III other instances the radiator pipes have been filled withwater, and the same is caused to circulate through such radiator pipesby heat imparted to the water.

In buildings, especially those covering a large area, and extending to aconsiderable height, difficulty is experienced in causing the steam heatto extend, with reasonable uni formity, to all parts of the building,because the radiators are of such a large capacity that the steamexpands into such radiators as are nearest to the boiler, and these haveto become heated before there is sufficient pressure for the steam toreach the other parts of the building. In my present invention theradiators are constructed in a peculiar `manner as hereinafter describedand they are filled with a non-freezing liquid, preferably a saturatedsolution of salt, and there is a pipe passing through the base of suchradiator, by which steam heat is availed of; hence not only does thesteam rapidly reach all parts of the building, and heat the same withapproximate uniformity, but the water in the radiators, retainsconsiderable heat for warming the rooms after the steam supply has beenshutoff.

In the drawings Figure l. isa sectional elevation ofthe end portions ofthe radiator, and Fig. 2. is a section crosswise ofsuch radiator.

The base A is preferably made of a wrought iron tube rolled in such amanner that the upper part thereof is thicker than the lower part, andthis tube A is screwed or otherwise serai No. 355.414. (No model.)

fastened at the end to the heads B, B, which may be provided with feetor flanges to rest upon the floor and support the radiator. Along theupper part of the radiator base A a range of holes is bored and screwthreaded for the reception of the vertical pipes C. which pipes arepreferably of wrought iron, and each one is provided with a removablecap 2. screwed upon such pipe for the purpose hereinafter stated. Apipe, D, passes longitudinally through the tubular base A, and it may bemade of copper; said pipe D is shown as screwed. at one end into a headB, and at the other end it passes through the other head B,

and is secured by nuts. The ends of the pipe D are screw threaded fonthereception of the couplings or connections to the steam pipe F and escapepipe G. for the water of condensation and within the. vertical pipes C,there are diaphragms or partitions 3, preferably of sheet metal, andhaving the lower ends bent diagonally as at 4, and these ends preferablyrest upon the steam heating pipe D, but the upper ends of the partitions3, are at some distance, say four or live inches, from the when the caps2, have been removed, or suiciently loosened, the radiator is to befilled with brine or similar material that is allowed to rise within thevertical pipe C, until it stands about midway 'between the upper ends ofthe partitions 3, and the caps 2. after which these caps 2. are screwedon tightly. When steam is connected with the pipe D it blows through thesame with comparative freedom and the water of condensation passes offvby the pipe G. in any usual manner; and air valves are to be providedin proper places in the building, either automatic or otherwise, toallow for theescape' of air; or circulating hot water may pass throughthe pipe D, instead of steam. The heat from the pipe D, is imparted tothe water within the radiator, and there will be a reliable and rapidcirculation up each pipe at one side of the partition 3. and down theother side of such partition, especially in view of the fact that thediagonal end 4, of each partition directs the heated` water up one sideof such partition, as devnoted by the arrows, and the cooler water de-IOO 75 screw caps 2. Itis now to be understood that scends with rapidityto take the place of the ascending column of warmer Water. For thisreason the radiator will be heated uniformly, or nearly so, from end toend, and the steam may be shut olf at any time when the temperaturebecomes sufficiently elevated; and all parts of the radiator can be madesteam tight, hence there will be little or no loss by evaporation ot'the water, but the spaces between the water line, and the caps 2. allowfor the expansion of the water as its heat is increased and this spacemust be sufficient to prevent the rupture of any part of the radiator bythe pressure generated by the heat; and in consequence of the water linebeing at the proper distance above the upper ends of the diaphragms orpartitions 3. the circulation of the Water can be always depended upon,but should the water line descend below the upper ends of the partitions3. the circulation of the heated water will be prevented; and shouldthere be any leakage that allows for evaporation of the water, the caps2. can be quickly loosened and water added sufficient to bring the waterline up to the proper level.

. I claim as my inventionl. The combination with the base A, of thevertical radiatingtubes C, attached to and opening into the base A aheating pipe passing into such base, and partitions within the verticaltubes, the lower ends of which are inclined substantially as and for thepurposes set forth.

2. The combination in a Wrought. metal radiator of a tube A, and.removable screw ends B. forming the base, a heating tube within saidbase, vertical tubes C. screwed into holes in the tube A, removable capson the upper ends of the tubes C. and partitions within the tubes C.with their lower ends adjacent to the heating tube substantially asspecified.
